PROCESS OF MIXING INGREDIENTS.

Specification of Letters Patent.

Patented Sept. 11,1906.

I Application filed February 27,1904. Serial No. 196,664.

To all whom, it may concern:

Be it known that I, ALEXANDER Q. NASH,

a citizen of the United States, residing at Sherman, Texas, have invented a Process of Mixing Ingredients, of which the following is a s ecification.

his invention relates to a process of mixing ingredients, and particularly by mixing ingredients first in the dry state and afterward saturating the material to the desired degree of moisture; and the object is primarily to mix ingredients in this manner to prepare sand-lime composition for building material; butthe same process will answer for mixing material and coloring-matter for making shale brick. i 7 Other objects and advantages will be fully explained in the following description, and

particularly pointed out in the claims.

Reference is' had to the accompanying drawings, which form a part of this applicat1on.

v Figure 1 is a side elevationof suitable ap; paratus for carryingout the objects of this invention. Fig. 2 is .a broken sectional view showing a portion of the mixing-chamber and a portion of the1moisteni ng chamber and illustrating'the mannerof; moistening the mixed material.

Similar characters of reference are used to indicate the same parts throughoiit both I, The apparatus illustrated. in the aceompanying drawings willbe sufficient forcarrying out the objects of this invention, and the apparatus shown illustrates one way of carrymg out the process. v

In thedrawings is shown a hopper 1, connected to a draft ipe or chamber'2, which is the dry-mixin cliamber. This chamber is connected to a last-fan 3, which is supported on a suitable framef4;". Th1s fan may be driven by any suitable power. Lshow a pulley 5, mounted on the fan-shaft anddriven by abelt 6,which belt is driven by a }i ul1ey- 7, mounted in-. suitable bearings 8.

hepulley 7 maybe driven by any suitable power.

At the juncture of the dry. chamber 2 and the margin-chamber 9 is provided means for the introduction of steam or an air-blast and water or other liquid. A moisteni -chamber 10 surrounds the end of the dr dliamber 2. A steam or air-blast pipe 11' communi- I cates with the chamber 10,. a'nd a pipe 12 for water or other liquid also communicates with chamber 10. The chamber 10 has perforations 13 in one end for forcingthe water and steam out, of the chamber 10in the form of spray. The mouth of the moisteningchamber 9'is flared and telescopes on the chamber 10. This construction will serve to deflect the spray towardthe center of the chamber 9. V, The water and steam may-be forced into chamber 10.with any degree of pressure desired. After. the material is thus moistened .it may bedelive'red in any one of the bins 14,15, or l6 to be delivered to the press. Swingin doors 17 and 18 are mount: ed in the cham er so that the passages fromchamber 9 may be closed or opened at :will. The door 1-Z is shown openingthefpas- These vanes may be moreorless deflected by [setting the vanes at different angles by means of thumb-screws 20. Suitable nuts 21 are made stationary on chamber 2, and

the thumb-screws or bolts '20 operate through these nuts. The side ofthe hopper 1 projects slightly down in the chamber 2 at 22, so

material back up into the hopper.

-'-- Any suitable mechanism may be used to place the ingredients'in the ho -per in the right proportion after the ingre lentshave that the blasts from the fan will not blow the been reduced or pulverized to the proper degree of fineness. -The blastfan 3'is rotated with suflicient velocity to force the material through the chambers'2 and 9. In manufacturing building material from sand-lime composition itis desirable to coat the grains ,of sand with the powdered lime. As the sand falls from the hopper it will be forced through the chamber 2 by-the blast; but the sand will travel slower thanthe. powdered material or lime. This makes the opportunity for the owder to strike the grams of sand and to orm a coating on the same. This operation ma be. accomplishedinthe chamber 2 either wit or without the deflecting-vane 19. The

vanes 19 may be necessary in some composi I forced'into the moving material in the form 2 in the dry stateby the blast from the fan, it passes to the mixing-chamber 9 to be saturated with water 'or other liquid, which is,

of spra The moistened material will thus be still kept in motion, although it has become heavier by being moistened, the pressure-of the steam and water aiding the blasts from the fan. It may be desirable to saturate thematerial with different kinds of solutions which may be forced in through the pipe 12. With the a paratus and with the process above descri ed in edients may be mixed to form brick or bloc or slabs and articles of similar, composition for building urposes. The brick or block or slabs may e made from compositions of different kinds of materials Afterthe materialis saturated to the desired de ee of moisture it may be deliv- -ered to suitable bins to be delivered to. the

presser.'

The above process is accomplished readily with the apparatus herein described, he principal feature of which is the blast from the fan or blower. The blastmay be created by other means than the fan or blower. The

rocess may be carried out with any equivaent mechanism. Building material is re ferred to above as being prepared by this process. It is apparent that ingredients for other purposes-may be mixed by the same process. The process consists in mixing the ingredients thoroughlyin the. dry state by means ot a blast, saturating the mixed ingredients to thedesired degree of moisture under ressure, and still further agitating the mixed ngredients to make the mass of material assume a uniform consistency before being pressed.

Y r Hayin'g fully described my invention, what I claim as new, and desire to secureby Letter-sPatent,is

1. The herein-described process of mixing finely-powdered and coarse ingredients consisting of mixing the ingredients in suitable roportions, treating the mixed ingredients in the dry state in a suitable chamber by means of a blast whereby the coarse material is coated with finely-powdered material, and

then saturating the mixed ingredientsto'the desired degree ofJmoisture.

2. The herein-described process of mixing light ingredients with heavy ingredients consisting' of mixing the ingredients in suitable pro ortions, coating the heavy ingredients wit light ingredients in the dry state by means of'a blast, saturating the mixed-"ingre. 0o dients to thedesired degree of moisture, and- -agitating the moistened mass of material.

3. The herein-described process of mixing heavy and light ingredients consisting of mixing the ingredients in suitable proportions and of the proper degree of fineness, treating the mixed ingredients in the dry state whereby the heavier material is coated withfinelypowdered material, and saturating the mixed ingredients to the. desired degree of moisture. 7 o
